I have updated my initial post to this thread:
http://www.the370z.com/track-autocro...ml#post2568224

I have not updated all my following posts, but I would ignore them. I tried to read all my old posts here and they were too embarrassing so I had to ignore them. This is a really old thread and we hadnt done much testing with different setups at the time.

You should have no trouble with 1.8s with the setup you listed. 1.6s? Maybe... if you are bias-ply its probably possible. But running at stock height will be the game changer.. lowering the car effects its ability to hook up much more than I ever realized previously. We have found a night and day difference.

Those GT-R turbos are going to spool hard and hit hard. Make sure to get a boost control system in place that can ramp the boost in. You can keep the instant spool sensation and let it hit a few psi right away but you dont want full boost until near redline. This boost control will help your project greatly in each department: traction, engine longevity, drivetrain component health.

Thanks for the updated information. I'll give the 28x10.5 bias ply 17's a shot first with the raised height and alignment.

Wonder if a dynalite caliper can be packaged over the 11.5" rotor to fit a 15" wheel......

I was going to go to 15 inch in back. I'm guessing just change the caliber and rotors and the 15 inch wheels will fit?

Correct... Just swap the rears for 370Z Base Brakes & Calipers.

I run 15's

I contacted TCE brakes about a wilwood adapter and it's not possible as a bolt on affair. So oem brakes it is.

Digging up this old thread for reading. Good stuff in here.

Phunk is dead on. When my car hooks it is fun as hell. Spinning is not much fun. When JCHammond got out of my car he was feeling his face with all of his fingers. LMAO, He felt it pull so hard it messed with his face. Instant wrinkle removal facial. I was supposed to go down and give my best friend a ride tomorrow. It's just too cold. He won't get the full experience so I am not going.

Will 17in Weld wheels fit with the Akebono rear brakes?

Got it figured out, nevermind.

Man I just watched Adam LZ blow another motor.. That's not what got me. He did a 1.58 60ft on 18" radials. Prior to that he hit 11.7 at 126 rolling out of the box.
I'm off the fence. Earlier I ordered a set of 17" Welds. I'm definitely running a 10 second 1/4 in 2020. I dont care if it's a 10.9 I'm running 10s.
Wheels ship in January so I'll most likely hit it in February and hopefully make another run at the half mile with traction control off this time.

What's your current setup, wheels and forced induction setup and hp?

15 nismo, HKS Hipermax SP coils, Z1 Diff Bushings, Subframe bushings, Wavetrac. Rays 19" 57CRs, 285f ,305 R888R.
Boosted Performance single with 6870. S1SE fuel system, 1300 ID Injectors, 340 in tank twin 450s in Radium Surge.
IPP Stage two 10:1 compression, JWT S2 cams, Zspeed 6 puck stage 4. Flex tuned by Seb.
WHP is questionable now since the last dyno was done with a boost leak and a crack in the manifold flex bellow. Made 710rwhp and 623ftlbs @ 18psi. Current High boost map is 21psi with a 23psi boost cut. I have not a single doubt the car has 10 seconds in it.

Naah, I think you're good,

:( My wheel money went to a new washer and dryer. Who is Adam LZ???? Another one of your fruity Floridian's?

If anyone is in need for a set of 18" racing wheels, let me know. I have 2 sets available!

Brand, width and offset would be helpful!

TSW Nurburgring 18x9.5 and 18x10.5. How does $600 sound for the whole set with some old slicks on it, come pick it up.

It’s been awhile since I’ve been in this thread. I currently have 305/35/18 Hoosier drag radials on 18X10.5 TSWs.... best 60ft I’ve ever got on these was a 1.7.... I was speaking with a local GTR owner who was able to pull off running 28” M&H slicks on Enkei PF01s.... was wondering if these will fit on the Zs rear with the OEM Sports/Nismo brake setup.

Awhile back people were saying the smallest u could go with the oem akebono brakes were 18” for clearance ..:but I’ve recently heard and read of 17’s fitting wondering with the 28 x 10.5 bias ply setup like sirnixalot posted. Can any of u gentlemen confirm????

Attached is the pic of the GTR on the Enkei PF01s tuning the M&H 28” slicks

The 305/45 17 is basically a 28 seeing as it's 27.8. That's the size ET street R I have to run with Weld 17x10.5s with a 6.5 offset. I haven't mounted the tires yet but the wheels fit and clear the calipers. So a 28" bias ply should be on point.

Are you on stock height/suspension? Pls post up pics if possible when you get the tires mounted and fitted....BTW...where did you order/purchase your Weld Rim from???

I'm on HKS coils and will likely raise the car to stock height for my quarter mile attempts. I also got my wheels from Jegs. Pro tip: Be prepared to wait. I waited 3+ months for mine.

Also I'm not focused on a super setup I'm just looking for a 10.xx run. If I went out and ran a 10.8 on my first run I'm done. My next focus will be sorting the suspension for occasional track days and slapping on the Welds from time to time for roll races and 1/2 mile events.
